基于位移型控制方程的圆板热后屈曲分析

本文推导了圆板位移型热后屈曲方程，在设定挠度试函数后，由微分方程精确求出径向位移，然后用Galerkin法消去另一方程的残差，试函数由Legendre多项式构成，结果表明：本文方法是有效的，有关结果可供设计圆板时参考。

Thermal post-buckling analysis of circular plate based on displacement type control equation

The displacment type thermal post buckling control equations of circular plate has been deduced. The Galerkin's technique was used with Legendre's multinomial expansion as a trial function. It is shown that methed used in this paper is an efficient. Some results are of benefit to design of circular plates.
